Highlights
• Streamlines the protection of Oracle databases by simplifying collaboration between database and backup
administrators.
• Reduces storage requirements and frees up high performance storage for production use.
• Accelerates database backup times through a perpetual incremental approach.
• Simplifies self-service process to give database administrators (DBAs) greater control and independently manage
backups on their own schedule.
• Provides backup admins with complete visibility to all operations while automating back-end processes.
Fragmented Backup Processes Challenge DBAs and Backup Administrators
When it comes to database protection these days, the left hand often doesn’t know what the right hand is doing. Over the
years, the tools and processes that DBAs and backup admins rely on to ensure reliable data protection, timely recovery,
and consistent governance have become highly fragmented. In an effort to retain some control over backup operations,
many DBAs prefer the “dump-and-sweep” approach, resulting in a two-step process that requires the DBA and backup
admin to perform separate tasks using their own tools and utilize a shared storage area where data is handed-off. Many
DBAs prefer the dump-and-sweep approach for several reasons, including:
• Allowing the DBA to use tools they are familiar with, such as Oracle®
Recovery Manager (RMAN).
• Direct access to backup copies allowing the DBA to quickly execute recovery operations without having to request
assistance from the backup team.
• Control over backup schedules allowing the DBA to coordinate backups with other database maintenance tasks to
avoid overloading database systems.
• Helping the DBA avoid database crashes by making sure the transaction log space is properly maintained.
• Eliminating the need to grant additional security access to the database.
Unfortunately the widespread dump-and-sweep method of database protection creates blind spots and inefficiencies that
can prevent each side from understanding the complete picture and taking the best course of action. For example:
• DBAs cannot directly see or utilize older “swept” backup copies that reside off-site or on long-term storage, such as
tape or cloud storage.
• Full recovery from “swept” backups requires a much slower, two-step process.
• Backup admins cannot easily verify databases are being properly protected in case of disaster or retained according
to regulatory compliance requirements.
• Dump storage areas often utilize expensive, high-performance storage resources.
• Lines of accountability blur when data is lost, resulting in pervasive finger pointing.
So while the dump-and-sweep approach can be convenient and can provide a degree of self-service for DBAs, there are
important downsides that jeopardize the availability and integrity of database information.

Database Growth Increases the Risk of Business Impact and Failed Recovery
Relentless data growth continues to compound the challenges of protecting database information. It’s not unusual for a
database to double its size every 18 months, and with big data applications database sizes are breaking new records
every day. For the largest databases, backups can become a serious challenge as backup times begin to exceed 24
hours. This challenge includes a number of factors:
• Larger backup windows prolong the impact to database performance and availability.
• Longer backup time degrades the best possible recovery point objective (RPO) and reduces the maximum number of
recovery points.
• Longer backup time increases the amount of redo logs that must be processed during a recovery, degrading
recovery time.
• Hardware snapshots (crash consistent) can jeopardize data integrity.
As recovery objectives become increasingly stringent and database backups exceed realistic backup windows, traditional
backup methods, including dump-and-sweep, become even more inadequate.
A New Approach is Needed
A new approach is needed to support existing DBA and backup admin workflows while creating clearer lines of
responsibility with less finger-pointing. Ideally this solution should preserve the benefits of the dump-and-sweep method
without its tradeoffs and improve how DBAs and backup admins work together to protect database data. Finally, the
solution should scale to support massive databases and reduce the impact these operations have on the business. In
particular, this new approach should:
• Give the DBA the choice to execute backup and restores using their own tools or relinquish that responsibility to the
backup admin.
• Give the DBA full visibility over and access to the entire data lifecycle, including long-term copies.
• Give the backup admin complete visibility over database backups initiated by the DBA.
• Eliminate the waste of expensive, high-performance storage for backup copies.
• Dramatically reduce backup and recovery times.
With this new approach, IT organizations should be able to achieve greater levels of operational efficiency, data integrity,
business productivity, and regulatory compliance.

Veritas NetBackup™ Copilot for Oracle®
: A Revolution in Database Backup and Recovery
Veritas NetBackup™ Copilot for Oracle®
integrates native Oracle tools with the backup application and purpose-built
storage to create an optimized solution for the protection of Oracle that enables better collaboration between DBA
and backup teams. Copilot gives confidence that the database is protected, and assures that it is safe, compliant, and
accessible whenever it may be needed. There are several important elements that make this solution possible:
• NetBackup appliance storage—Utilizes a NetBackup appliance as the “landing pad” for all RMAN-directed
operations, via a NFS share. Database shares can draw additional capacity on-demand from a shared pool.
• Deep Oracle RMAN catalog integration—Keeps the RMAN catalog synchronized with all NetBackup database
copies available within the data lifecycle.
• Accelerator for Oracle—Provides “incremental forever” backup method by leveraging Oracle® Incremental Merge
technology without scripting. Space-optimized full backup images are automatically synthesized to prepare for fast
recovery.
By more efficiently utilizing backup storage space with a single pool of storage for all backups in the environment,
NetBackup Copilot eliminates storage redundancy between native tool backup and application agent backup. This results
in fewer storage locations to manage for space and access while freeing up high performance storage for production
use. Because NetBackup Copilot reduces the load on the network and the Oracle database, performance is no longer
impacted as heavily by increasing data volumes.
Attribute Traditional approaches NetBackup Copilot for Oracle
Visibility for the
DBA
With dump-and-sweep, DBA can only see initial copies
he creates using RMAN.
DBA can see all backup copies across the entire lifecycle
within the Oracle RMAN recovery catalog. All subsequent
copies made by NetBackup are synchronized with Oracle.
Visibility for the
Backup Admin
With dump-and-sweep, backup admin only sees
database backup copies as nondescript files.
Backup Admin recognizes Oracle database backups as
distinct from ordinary file backups.
Business
impact
Database servers are impacted heavily for the entire
duration of the backup. Dump-and-sweep doubles the
impact to network and storage infrastructure.
Shifts processing and I/O burden to a dedicated
NetBackup appliance and eliminates the double data
move. Faster backups with Accelerator for Oracle reduce
impact duration on the production environment.
Storage
utilization
Space is required for “dump” area as well as “sweep”
area, doubling the storage requirement. Dump area
often uses high performance storage, and older copies
must be deleted to make room for newer copies.
Storage space is utilized on a NetBackup appliance (NFS
share) and is automatically maintained by NetBackup.
With Accelerator for Oracle, less storage is required to
store changed blocks.
Full backup
time
Full backups must be performed on regular (e.g.
weekly) basis.
With Accelerator for Oracle, traditional full backups are no
longer necessary (after an initial full). Oracle Incremental
Merge is used to synthesize new full backup images using
older backups and newer changed blocks.
Full recovery
process
For dump-and-sweep, recovery is a two-step process
requiring the same data to be moved or imported twice.
Data is restored directly into Oracle.
Recovery time For dump-and-sweep, full recovery time is effectively
doubled. Redo log processing time also increases with
the time between backups.
Full recovery does not require a two-step process. With
Accelerator for Oracle, full backups can be run more often,
so fewer redo logs must be processed during a recovery.
Recovery
flexibility
DBA must request assistance when restoring older
database copies that are not on storage he has access
to.
DBA has access to all backup copies throughout the data
lifecycle, including copies created by NetBackup.
NetBackup Copilot works for all NetBackup supported versions of Oracle.
